63rd RRC:RSC

The 63rd Regional Readiness Command (RRC), previously known as the 63rd Regional Support Command (RSC), traces its lineage to the 63rd Infantry Division, which was activated during World War II and earned distinction in combat across Europe. After the war, the division was re-designated and reorganized as part of the U.S. Army Reserve, evolving into the 63rd RSC in the post-Cold War era. Headquartered in California, the 63rd RRC provided administrative, logistical, and operational support to Army Reserve units across several western states. The command played a vital role in mobilizing and supporting Reserve forces for overseas operations, including those in Iraq and Afghanistan, until its functions were realigned under the 79th Sustainment Support Command in 2008.
